Find the area of the shaded region. Round your answer to one decimal place if required.

98.2 square meters

Step-by-step explanation:

Area of shaded region = area of right triangle + area of semicircle ( r = 4 m)

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
